ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No} 271,156, dated January 281, 1883.

Application filed September 22, 1882. (No model.) Patented in Belgium March 17, 1882, No. 57,377; in England August- 19, 1882.

No. 3.992, and in France August 28, 1882.

To all whom it may concern Be it known that L'JULES MARIE XAVIER TERLINDEN, a Belgian subject, residing at Brussels, in the Kingdom of Belgium, a retired superior officer of the Belgian army, knight of the order of Leopold, have invented new and useful Improvements in Rotary Engines Applicable as Motive-Power Engines or as Pumps, (for which I have obtained a patent in Belgium, No. 57,377, hearing date the 17th of March, 1882, and for which application for Letters Patent has been made in England on the 19th of August, 1882, No. 3,992, and in France on the 28th ofAugust, 1882,) of which the following is a specification.

My invention relates to that class of rotary engines-in which radial pistons or vanes slide to and fro in slots formed in a drum or hub mounted eccentrically in a cylinder or casing; and it consists in the improvements, hereinafter described, by which the required motion is given to the pistons or vanes, and the sides and ends of the said pistons or vanes are caused to work fluid-tight in the cylinder or casing. I attain these objects by the mechanism illustrated in the accompanying drawings.

Figure 1 is a cross-section, and Fig. 2 an elevation, 0t a rotary motive-power engine constructed according to my invention. Fig.3 is a front elevation of part of one of the pistons. Fig. 4 is an end view of the same. Fig. 5 isa cross-section through the line E F. Fig. 6 is horizontal section through the lineCD. Fig.

7 is a horizontal section through the lineAB.

Fig. 8 is a horizontal section through one of the covers of the cylinder or casing. These figures-from 3 to 8, inclusive-are made upon a somewhat larger scale than Figs. 1 and 2. Fig.9 represents in cross-section, and Fig. 10 in longitudinal section, a portion of the e11- gine, and show another 'way in which the parts can be constructed. Figs. 11 and 12 are details showing metal bands, hereinafter de scribed. Figs. 13 and 14 respectively represent in cross-section and longitudinal section my engine applied as a pump. Figs. 15, 16,

17, and 18 are details, respectively, showing sectional views of the piston, as hereinafter described.

\Vithin a suitable cylinder or casing, a, provided at each end with a suitable cover, It, and upon an axis, a traversing the said covers eccentrically to the center of the said cylinder or casing a, I mount a cylindrical revolving drum, 1), so that a part of its outer surface is constantly in contact with a part of the inner surface of the cylinder a or a metal plate, as, inserted therein, and adjustable by means of a set-screw or otherwise.

In the drum 1) are four radial slots, b, forming slides, in which slide in and out the pistons or vanes f, so arranged as to be at their outer ends constantly in contact with the inner surface of the cylinder or casing a.

c c are two steam-chambers--one for the in- 6 let and the other for the exhaust of the steam or actuating-fluid. The said chambers communicate with the outside of the cylinder or casing by the pipes at d, and with the inside of the said cylinder or casing by suitable ports,

as seen in Fig. 1. The two chambers c c together present somewhat the figure of a crescent divided in the middle and separated from the interior of the cylinder or casing by suitable partitions, as shown'in Fig. 1, and, according as the actuating-fluid is caused to enter at d or d, one or the other of the said chambers 0 will be for the inlet of the said fluid and the other for the discharge of the same.

Two of the said engines a a are placed end to end, as seen in Figs. 1 and 2, (the parts of the engine a being shown in dotted lines in Fig. 1.) Each of the engines may be actuated separately and be worked at the same pressure; or the steam or fluid from one of the-cyl- 8 inders may be caused to pass into the second cylinder, to act expausively therein. In both cases theen gines will be caused to work continuously, uniformly, and regularly, for, the pistons or vanes ot'oue ofthe engines being set atan oo angle of forty-five degrees to those in the other engine, the unequal velocities imparted to the shaft by each of the drums equalize each other eight times and compensate each othereight times during each revolution of the drums. 93

A two-way cock, 0, enables the steam or fluid to be cutoff as required, or the motion of the engine to be reversed.

hen regularity of motion is not required a single engine may be usedinstead of two, as hereinbefore described, such single engine being provided with two, three, or four pistons or vanes. The said engine being symmetrical, the pistons or vanes may be caused to revolve in either direction, according as the steam or fluid enters at d or at d, or as the drum 1) is .mounted upon its axis.

1 will now proceed to describe the arrangement for causing the drum 1) and pistons or vanesfto work fluid-tight against the covers of the cylinder at, and for causing the outer ends of the said pistons or vanesfto work fluidtight against the inner surface ot' the cylinder or casing a, and also for causing the said pistons or vanesfto slide in and out of the slots 2), as required.

In order to make the ends of the drum work fluid-tight with the covers of the cylinder, each of the ends of the drum is covered by a disk, g, affixed to it, Figs. 3 and S, a part of the said disks 9 being made to enter and work in a depression formed to receive it in the covers h.

In order to make the ends of the pistons or vanes Work fluid-tight with the inner surface of the cylinder or easing a, the outer end of each of the said pistons or vanesfis formed with a cavity or groove, in which fits a metal roller or tube, i, (which may be solid or hollow.) The said roller or tube t' projects upward slightly above the end of the piston or vane, and is capable of partial rotation therein. It also projects beyond the sides of the piston or vane, and the projecting ends of the said roller or tube fiteach into a circular groove, 9', formed in the covers it h, the width ofthe said grooves being rather less than the full diameter of the said roller or tube. The said grooves j serve as guides to the pistons or vanes, caus ing them to slide in and out of their slots 1) during the rotation of the drum 1), so as to keep their ends constantly in intimate contact with the inner surface of the cylinder or casing a. The upper parts of the rollers or tubes 6 are throughout their length, at 75, Fig. 4, curved to the radius of the cylinder or casing .a, and at their opposite side, at l, where they enter the grooves they are curved concentrically. The reduced diameter of the roller or tube at k and lenables the ends of the said roller or tube to engage in the said grooves j. If it be desired to increase the contact of the ends of the roller or tube .i with the groovej,

.the ends of the tube 2' may be fitted with a separate plug or end piece, i, Figs. 3 and 7, arranged so as to be pressed outward by the action-of the steam or fluid.

The sides of the pistons or vanes fare made 1), being pressed upon by the steam or fluid-on one side of the piston or vane f, opens one of the apertures 0 0 and closes the other. The steam or fluid enters the passage 0, passes up into the tube 2', where it presses the plugs or end pieces, t", into the grooves j, and, passing down the said passage 0, enters the slot or slide 1), presses forward the piston or vane f against the inner surface of the cylinder or casing, and, entering'thelpassages n, presses the plates m against the cylinder-covers.

In Figs. 9 and 10, a is the outer cylinder or casing; I), the rotary drum, formed with slots. or slides b, in which the pistons or vanes slide. The said pistons or vanes c consist of' two parts, 0 0 which work one within the other, like the tubes of a telescope. In some cases the'said pistons or vanes may be composed of more than two parts working one within the other telescopically. The admission and discharge of the steam or fluid, instead of being effected at opposite sides of the cylinder or casing, as in Figs. 1 and 2, are effected at d dthat is on each side of the point'ot' contact between the drum 1) and cylinder or casing a. The pistons or vanes are made semi-cylindrical at their outer ends, with a projecting cylindrical stud at each side, to take into the grooves e, and the said studs may be covered by metal ferrules or rings connected together by segmental bands, as represented in Figs. 11 and 12, the said bands covering and protecting the outer end of the piston or vane. The said ferrules and segmental bands may be flattened, as represented at 7c and Z, Fig. 4. This arrangement is used in substitution for the rollers or tubes 1' represented in Figs. 3,

The bottom of the circular groove at, 5, and 7. 0 may be provided with a flat annular plate, rendered adjustable by set-screws traversing the cover, or otherwise.

The sides of the drum 1) and of the pistons or vanes in Figs. 9 and 10 are made to Work fluid-tight in the cylinder a by the covers of the said cylinder or casin g being each provided with an inner adjustable cover or plate, g, carried and guided by pins or studs 9 projecting from the outer cover, or by other suitable means; and the said inner covers, g, may be adjusted in position, and their contact with the drum 1) and pistons or vanes may bemaintained, so as to insure their working fluid-tight, as required, by means of set'screws h h, or otherwise.

The shaft of the engine rotates directly in the outer covers which are provided with suitable stuffing at i to prevent the escape of steam. The said motive-power engines may be actuated either by steam, air, or any other suitable fluid.

In small engines to be worked at a high speed and to revolve always in the same direction I cause the steam to enter through the drum shaft. The steam is caused to pass through suitable ports formed in the said shaft and opening into the slots of the drum, where it presses forward the pistons or vanes against the inner surface ofthe cylinder or casing, and, passing into the said pistons or vanes through suitable passages formed therein, it issues out through suitable openings into the spaces between the pistons or vanes to propel the enine.

Figs. 13,14 represent in cross-section and in longitudinal section, respectively, the application of my invention to a pump. a is the outside cylinder or casing. 12 is the drum, in the slots or slides c of which drum two pistons or vanes, (I, work. a and a are the inlet and outlet passages for the liquid, and e is the shaft or axis upon which the drum bis mounted. As hereinbefore described with reference to Figs. 1, 2, 3, 4, 5, 6, 7, and'S, the ends of the pistons or vanes 61 are provided with rollers or tubes t, (represented in detaihdrawn to a larger scale in Figs. 15,16, and 17.) The ends of the said rollers or tubes 2', as in the motive-power engine above described, Figs. 3 and 4, project beyond the pistons or vanes, so as to take into the gr'oovesj, which act as guides. The said rollers or tubes t' are closed at their ends by plugs or pistons t", pressed outward by the spiral screw F. The rollers 1' may be made solid instead of being tubular, and the spring i may be dispensed with; or the rollers or tubes i may be dispensed with altogether by making the'ends of the pistons or vanes of semicircular section, with a cylindrical stud or projection at each end, and covering the ends of the pistons or vanes-and the said studs or projections with ferrules or metal rings and segments, asrepresented in Figs. 1]

and 12. If required, a small channel, I, Fig. 18, may be made from the outside to behind the pistons or vanes to facilitate the action of the said pistons or vanes in their slots or slides.

As it is not necessary that the pistons or vanes of pumps should work as perfectly fluidtightv as those of motive-power engines, the sides of the pistons or vanes and of the drum work directly against the covers, as seen in Fig. 14. The cylinder-covers may, however, be provided with adjustable innercovers or plates similar to those represented at 9, Fig. 10.

In some cases the width of the circular grooves j may be equal to the whole length of the piston or Vane, which then has the formof a rectangular parallelopiped having on one side a rounded or semi-cylindrical surface and on the other two recesses-one at each end. The parts subjected to friction may be covered with removable pieces of soft metal, as hereinbefore described.

There the pump is intended to supply small quantities of liquid the piston or vane is simply a roller.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the sliding piston, of the plates m, located in grooves in its side edges, and the steam-passages f, whereby the steam will force said plates against the ends of the cylinder, substantially as described.

2'. The combination, with the sliding piston, of the hollow roller t, provided with movable plugs 71, and the steam-passages formed in the piston and connecting with the interior of the roller, whereby the expansive force of the steam will force the plugs outwardly, substantially as described.
